Abstract

Ichnofossils Arenicolites, Didymaulichnus, Gordia, Helminthopsis, Monomorphichnus, Phycodes pedum and Planolites A, B and C are described from the Late Precambrian -Middle Cambrian Pele La Group exposed in the Tang chu - Wachi La sector of the Bhutan Himalaya. The Precambrian-Cambrian boundary in this section is tentatively placed below the Phycodes pedumlevel, in the middle part of the Maneting Formation.

The volcanics of the Singhi Formation, occurring at the base of the Pele La Group represent an important Neoproterozoic event.
